A number of people who have preordered Call of Duty: Infinite Warfare are reporting they have received codes that appear to be access to a beta at some point in the future. The first reports started on Neogaf when a user received an email from Amazon giving them a code for a “future pre-order offer.”
In addition to this report, we also recently learned that DLC for the game is going to be coming to the PS4 before the Xbox One. We don’t know when the beta is coming but the full release of Call of Duty: Infinite Warfare is due this November.
